Abstract: The critical opalescence of a binary polymer mixture consisting of polyvinyl methyl ether and deuterated polystyrene was measured by small-angle neutron scattering. In accordance with a mean-field treatment, it was found that the critical exponents $\vartheta$ and $\gamma$ are 0.5 and 1, respectively ; the Ornstein-Zernike scaling function describes the scattering data ; and the spinodal is parabolically shaped. However, the dependence of the interaction parameter $\overline{X}$ on the composition of the polymer mixtureis in conflict with the theoretical result. Further it was experimentally demonstrated, that the conformation of the single chain does not insignificantly alter insite the error bars in a very wide temperature- and composition range.
